Hi All - I'm so discouraged.... after 2 rounds of antibiotics, Simba had about 10 good days and then last night he started showing symptoms of a UTI again. This morning he was no better. This has been ongoing for 1 month now. I have an appt. tonight with the vet. I know they will want to do a urinalysis. Is there anything specific I should ask the vet to check? When he was in a month ago they did a urinalysis and said there were no crystals, just a mild UTI. They also did an x-ray and said there were no stones of any kind. He's already been on Clavamox and then Zenequin. Any idea what the vet will do for him from here? More antibiotics? It just puzzles me how he can be fine for 10 days and then revert back.
